通过在Unity中滑动来翻译对象

Question

I am trying to translate my sphere while swiping my finger on the screen.
With the code below I need to swipe again and again to move it forward. How can I translate an object forward by swiping only once?

public float speed;

void FixedUpdate ()
{  
    if (Input.touchCount > 0 && 
        Input.GetTouch(0).phase == TouchPhase.Ended || (Input.GetMouseButtonDown(0)))
    {
        transform.Translate(Vector3.forward * Time.deltaTime*speed);
    }
}

Answer 1

Your code makes the object move for the exact moment when the TouchPhase has Ended. In order to push the object, try applying a force.

Modified C# example from Unity Tutorials :

public float speed;
public Rigidbody rb;

void Start() 
{
    rb = GetComponent<Rigidbody>();
}

void FixedUpdate() 
{
    if (Input.touchCount > 0 &&
        Input.GetTouch(0).phase == TouchPhase.Ended || (Input.GetMouseButtonDown(0)))
    {
        rb.AddForce(Vector3.forward * Time.deltaTime * speed);
    }
}

You need to add a Rigidbody3D Component to the object, if you use this technique.
